Food intolerance vs. food allergy

Food intolerance and food allergy are two different diseases. The following table shows how these two diseases can be distinguished from each other:

Food allergies Intolerance to food
Relationships with the immune system Food allergy is a reaction of the body’s immune system. The body’s immune system mistakenly reacts to certain food proteins as a threat to the body. What we call allergies. Food intolerance has nothing to do with the body’s immune system. It does not cause any allergic reaction.
Symptoms of the disease – Rash or itching of the skin
– Swelling of face, lips and throat
– wheezing like asthma during breathing
– Skin rash and itching – Abdominal pain, bloating, flatulence – thin stools
When symptoms appear Symptoms usually appear very quickly after eating certain foods. Symptoms usually appear gradually after a few hours of eating foods that are difficult to eat.
The amount of food The reaction starts after eating a very small amount of food. Symptoms usually appear after a certain amount of food.
Death risk Food allergies can sometimes be fatal. Food intolerance is never fatal.
Examples of specific foods Adults are usually allergic to certain foods. E.g.
Various nuts, including shrimp, squid and other shellfish

Children are usually allergic to the following foods:
Milk, eggs, fish, peanuts and other nuts

Patients with food intolerance may have intolerance to many types of food. E.g.
Milk and dairy foods, wheat foods and foods with a variety of additives and preservatives

Causes of food intolerance

It is not always easy to understand why a person cannot tolerate certain foods. In some cases the relationship between food and symptoms gives an idea of ​​the cause of intolerance.

For example, milk, yogurt and soft cheese contain a type of sugar called lactose. Many people’s bodies cannot digest this lactose.

Therefore, if symptoms of intolerance appear after consuming milk and dairy products, the patient may be presumed to have lactose intolerance.

In this case, with the advice of a doctor, you have to be sure about this disease and take proper treatment.

Some people have problems digesting wheat or wheat-based foods. In this case, after eating bread made of wheat or bread, there are various symptoms such as flatulence, abdominal pain, flatulence, diarrhea and nausea.

In addition, various preservatives, additives and other chemicals added to food can often cause intolerance. These include:

  • Testing salt or MSG (monosodium glutamate)
  • Artificial colors, flavors, essences and preservatives used in food
  • Artificial sweeteners used as sugar substitutes. Such as: Xerocal, Sugar Free, Equal and Huxel
  • Caffeine
  • Alcohol
  • Different germs or toxins made from them — these contaminate food
  • A chemical called histamine. It can be found in mushrooms, processed foods and alcoholic beverages

Food Allergy And Food Intolerance: Know The Difference And Why You Must Not  Ignore Them

Ways to identify food intolerance

The best way to determine if a particular food is intolerable is to:

  1. Observe the patient’s symptoms and eating habits
  2. Find out if there is any link between the patient’s symptoms and the specific food

If there is any doubt about a food, remove it from the food list for a while and see what the result is. Then you can slowly add the food to the diet again. You can also write this information in a diary.

Food diary

The following 6 facts should be written in the diary:

  • What kind of food is being eaten
  • Whether there are any symptoms after eating those foods
  • What kind of symptoms are appearing
  • What are the symptoms?
  • Whether the symptoms improve after skipping the meal
  • Whether the symptoms are returning after re-adding the omitted food to the diet

Trial Elimination Diet

Foods can be excluded from the diet one by one after an idea has been formed about which foods are causing the symptoms in the body. This method is called ‘Trial Elimination Diet’.

Food that is thought to be intolerable should be removed from the food list for 2-6 weeks to see if there is any improvement in the symptoms.

Then add the food to the diet again to see if the symptoms come back. It may be that eating up to a certain amount of food is not a problem. But if you eat more than that amount, the symptoms appear.

Consult a nutritionist or dietitian to ensure that the body receives all the nutrients during this procedure.

Special Note: In the case of children, never stop feeding certain foods without the advice of a doctor or dietitian.

Domestic treatment of food intolerance

The only way to control intolerance to certain foods is to stop eating them for a while. Then little by little the food should be added to the diet again.

Again, it is important to observe the maximum amount of food that can be eaten before the symptoms appear. Then the food has to be added to the food list again.

To understand what kind of food to avoid, you need to read the labels of the food packets carefully.

If you think you have an intolerance to baby food, you must consult a doctor or dietitian before removing any food from the baby’s food list.

For example, many people exclude cow’s milk from their baby food list. Cow’s milk is a very good source of calcium, vitamin D, and protein. Therefore, if the baby’s body does not tolerate cow’s milk, it can be removed from the baby’s food list only after confirming the availability of necessary nutrients in alternative ways with the advice of a doctor.

When it is important to consult a doctor

If the condition does not improve even after eating according to the rules and the symptoms come back again and again, a doctor’s advice should be taken.

In addition, children with stomach problems (such as abdominal pain and diarrhea) should consult a specialist if they have any of the following symptoms:

  • If the child does not seem to be growing properly
  • If the condition does not improve even after eating according to the rules
  • If you suddenly have a bad reaction after eating any food
  • If you think you have a food allergy
